JERSEY, A CORPORATION OF NEW SHEET-METAL BAND FOR PIPE-COVERINGS OR OTHER LIKE PURPOSES.

SPECIFICATION forming part of Letters PatentNo. 755,679, dated March 29, 1904.

Application filed. January 14, 1904. Serial No. 188,971. (No model.)

To all whmn it may concern.-

Be it known that I, BERNARD H. LARKIN, a citizen of the United States, residing in Austin, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sheet Metal Bands for Pipe Coverings or wire loop being secured to the strip by folding the strip over the loop and inserting a rivet through the folded ends of the sheetmetal strip. This involves considerable expense for the wire loops and in the labor necessary for attaching the same.

The object of my invention is to provide a sheet-metal pipe-covering band of a strong, simple, and eflicient construction, which may be made out of one piece and more cheaply manufactured.

My invention consists in the means I employ to accomplish this resultthat is to say, it consists in a sheet-metal band for pipecoverings having one end slightly widerthan the other and its wider end furnished with a curved transversely-extending slit, the slitted portion having a straight fold upon itself to form an opening for the insertion of the other end of the band-strip and to form a straight smooth bearing for such inserted free end, so that it may be drawn tight and then folded as required. This folded slitted portion also strengthens the integral loop thus formed at the wider end of the band-strip, and the integral loop is also further strengthened and prevented from tearing by a narrow hem or fold which is formed in the sheet metal around the same.

In the accompanying drawings, forming a part of this specification, Figure 1 is an elevation of a horizontal pipe and its covering provided with my invention. Fig. 2 is a crosssection on line 2 2 of Fig. 1. are plan views of the strip looking from opposite sides. of Fig. 3.

In the drawings, A represents the pipe, B the pipe-covering which is wrapped around the same, and D D are sheet-metal bands for holding the pipe-covering in place. Each of these bands consists of a long thin strip of sheet metal having a free end d slightly narrower than its loop end d. The loop end 0? is provided with an integral loop d, which is formed by providing the loop end with a curved transversely-extending slit d and then folding the curved slitted portion d on the straight transverse line d thus giving the eye or transverse opening of the loop a straight and smooth or rounded bearing W by reason of the fold (Z for the free end of the 'strap to bear and slip against when it is inserted in the eye or opening of the loop. To further strengthen the integral loop, the loop end of the strap is furnished with a marginal hem or integral fold d, which prevents any tendency of the loop to break or tear. To still further strengthen the loop, it is preferably provided with a surrounding bead or depression d 1. A pipe-covering band consisting of a long thin strip of sheet metal, having an integral loop at on end formed by a curved transversely-extending slit, the slitted portion having a fold therein to give a smooth rounded bearing for the free end of the band, substantially as specified.
